Be it'linown that l, EDWARD F. FOLLIN,

a ycitizen of the United States, residing at Great Falls, in the county of Cascade and State of Montana, have invented certain new Yand useful Improvements vin Boiler-lVashing` Nozzles, of which the following is a specification. y

This invention relates to a. nozzle through which to deliver a stream of water against the internal surfaces of Va boiler, for instance, a locomotive boiler, and which is adapted to be manipulated to direct the stream in widely diverging directions and against widely distributed surfaces.,Y

The object of the invention is to `pro-vide a tool ofthe kind 'stated which is of simple and durable construction and which willrbe highly efficient in service; also to construct a tool which will be readily introduced through the comparatively restricted openf king aorded by the washout plugs of a locomotive boiler, and can be made to eii'ect the wide distribution of its cleansing stream before mentioned by backward and forward movements in the direction of rotation about its axis, and such slight angular motion as the open washout plug will permit; also to provide such a tool with an improved arrangement of handles that facilitate therma-A nipulations aforesaid.

In carrying out the invention, a water conducting .tube is provided and equipped at its rear end with handles extending, respectively, in the direction of the axis of the tube and in a direction substantially transverse thereto; and this tube is made to extend beyond its handles a distance equal to the range of penetration required for reaching, say, to the center of the boiler space, and4 has its forward end closed against the escape of water 1n the direction' of the axis of the tube, but provided with a jet opening or outlet nipple presented trans versely to the axis and preferably in a direction opposite to the transverse handle so that by rotating the nozzle through the me` dium of its transverse handle, a range of delivery may be developed equal to a complete circle, and by varying the degree of intrusion of the delivery end into the boiler, every portion of every surface within reach from the washout plug can be made to receive the impingement of the cleansing stream. The handles are provided with lgrips of heat nonconducting material, such,

for instance, as sections of rubber, fiber, or other hose, and the axiallypresented handle is preferably 'developed by applying over the pipe lend the f hose that conveys theA cleansing waterto the nozzle.'`

Preferably, the vnozzle will be provided with a valve in order that the'operative may cutoff the'flow of'water at will, and this valve may exist as aseparate instrumentality or as" a diametricallyperforated plug intersecting the bore of the pipe and proltruding beyond the same a distance suitable to provide thev transverse VhandleV through?.

which the nozzle is tobe manipulated.4

In order thatrthe invention may'be fully understood, three embodiments'thereof are illustrated in 'axial section in the 'accompanying drawings: Y f Figure 1 showing a form in which the controlling valve is omitted; Y

Figure-2 showing a' form'in which the controlling valve exists as a separate element in addition to the handles; and

Figure 3 showing a form in which the transverse handle and controlling valve are combined in a single structure.

AReferring to all of the figures, lk repre-Y sents aftube of sufli'ciently small diameterto Y pass freely through the washout plug of a locomotive boiler and having a diameter which throughout the length of the nozzle is less than that of the lstandard washout plug openings of locomotives, thereby providing a free and non-obstructing external form of sufficiently length to adapt it to enter the relatively small washout plug opening of a locomotive and reach the desired distance within the boiler,`say, to the center thereof. The front end 2 of the tubel is closed, and adjacentv thereto the tube is flattenedon one side, as at 3, and provided with a discharge port or nipple 4 which is accommo-V Y f handles, any or all of the described move!V ments in the manipulation of the nozzle may be developed at Will, the handle 5 serving especially as a means for developing rotation of the nozzle. The insulation 8 on the handle 7 is preferably the hose that brings to the nozzle the hot water commonly used for Washing out boilers.

If desired, the nozzle l may be provided, as shown in Figure 2, With a controlling valve 9 in order that the operative may control the delivery7 of Water through vthe nozzle and avoid .employment of an extra hand Who is generally in attendance upon the valve at the drop of the washout line when the Washing operation is going on.

As suggested in Figure 3, instead of the valve 9 extending as a separate instrumentality, a plug valve 9 'may be combined with the shank 5 that serves as a transverse handle, and a valve shell 10 can be introduced between pipe l and handle 7 in aV inanner to serve also `as the means for Vapplying the handle 5 to the nozzle. n Figures 'l and 2 the handle 5 is applied vby Welding-it tothe side of the pipe'l.

I claim:

l. VA boiler Washing nozzle, comprising a `tubular member adapted for intrusion through the washout plug opening of a boiler and having a lateral discharge orifice at its `intruded end, and longitudinal and transverse handles on said nozzle in rear of the intruding portion thereof; said discharge orifice comprising a delivery nipple; and the intruded end of the nozzle having a iiattened Wall in Which said nipple is inserted; the overall dimensions of the intruded portion of the nozzle including the nipple being less than the diameter of such an opening.

1 Washing nozzle constructed Ifor intrusion through the washout plug opening or" a boiler, and for angular, rotary, and longitu linal movement therein; said nozzle comprising a' tube proVidedWith manipulating means at one end Iand having ani'ntruding portion beyond such manipulating means Which isy of -uniform diameter or istantially the Whole length thereof, ,and is constructed at its end with a depressed side wall containing a transversely presented nipple Agerminating Within said diameter.
